P4 3GHz, Win XP MCE
8500GT GPU with H.264 h/w acceleration running
Cyberlink H.264/AVC Decoder (Azurewave) (from Twinhan Digital TV package)
Using VMR 9 renderer

Everything is working well. CPU is about 20% or less.
However, getting jitter which is most noticeable during panning. VMR9 renderer properties in DVBViewer is showing jitter of about 9 on Freeview HD demo channel (720p). Is better on TV3 - jitter is about 3 (1080i). Don't seem to be dropping frames.

Also showing frame rates of about 37 on 720p channels. What is that about??

I've read that there may be a problem with the Purevideo engine on 8500 & up Nvidia GPU's.

Do others have this problem? Is this an VMR 9 issue? What jitter readings are others getting?
